    Abstract: An electronic system includes a first LC oscillator connected to a first general-purpose input/output (GPIO) circuit and a second LC oscillator connected to a second GPIO circuit. A threshold generator is coupled to an input of the comparator. A control circuit is configured to control a measurement phase comprising a first capture phase and a second capture phase. A microcontroller is coupled to the control circuit and a power management circuit is configured to switch-off the microcontroller following activation of the control circuit by the microcontroller. The control circuit is configured to control the application of an excitation signal to the each oscillator via the respective GPIO circuit, control the GPIO circuit so that oscillations of the oscillator are provided to the comparator, and count, based on an output of the comparator, a number of oscillations in the oscillator exceeding a threshold output by the threshold generator.

    Abstract: A light sensor includes an integrated circuit chip and a boost DC/DC converter. The integrated circuit chip supports an array of pixels, each pixel including a SPAD. The boost DC/DC converter delivers to the SPADs a bias potential capable of placing the SPADs in Geiger mode. The boost DC/DC converter includes an inductive element, a first switch, a second switch, and a circuit for controlling on/off switching of the first switch. The inductive element and the first and second switches are arranged outside of the integrated circuit chip while the control circuit forms part of the integrated circuit chip.

    Abstract: In accordance with an embodiment, a system on chip includes: a plurality of master equipment; a plurality of slave resources, where a slave resource of the plurality of slave resources comprises a memory device includes a first memory area; an interconnection circuit; and a check circuit. A first master equipment is configured to define initial access rights for the first memory area, and to delegate access management of the first memory area to a second master equipment. The second master equipment is configured to define for the first memory area, particular access rights from the initial access rights associated with the first memory area and access right rules; and the check circuit is configured to check whether a transaction intended for the first memory area is indeed authorized to access the first memory area using applicable access rights associated with the first memory area.

    Abstract: In an embodiment, a radio frequency (RF) receiver circuit includes a main circuit and a wake-up circuit. The main circuit is configured to process RF signals. The wake-up circuit is configured to detect a reception of the RF signals. The wake-up circuit includes an automatic gain control (AGC) loop, and is configured to have a first operating mode where a set point voltage of the loop has a first substantially constant value, and a second operating mode where the set point voltage of the loop has a second value dependent on a power supply voltage of the wake-up circuit.
